JARRETT – ISOTECH WATER TRIPLE POINT CELLS

Internationally proven Water Triple Point Cells, ISOTECH isotech

תיאור

The Water Triple Point is the most important fixed point, the only point common to the ITS-90 and the Thermodynamic Temperature Scale. It is an essential reference point for every temperature laboratory. The Jarrett-Isotech cells are the best standard, all cells are not the same, accept no inferior device.

Total Confidence – The Internationally Proven Cells The Jarrett-Isotech cells have been in production since 1958. A independent comparison* in 1981 showed the first cell to be within 0.000006°C of the reference cell. The most recent international study organized by BIPM** consistently shows labs using both recent and older Jarrett-Isotech cells tightly grouped, tens of μK around the BIPM reference value.

International comparisons prove the quality of the Jarrett-Isotech Cells and are unique in the number, and history of comprehensive evaluations.
